Title: Rendering building materials hydrophobic
IPC: C04B41/49
Filed: 1974-11-11
Abstract: 1477720 Rendering building material hydrophobic WACKER-CHEMIE GmbH 11 Nov 1974 [9 Nov 1973] 48787/74 Heading D1P Shaped building materials e.g. glazed ceramic tiles, bricks, structures of natural and/ or synthetic stones, mortar, cement, asbestos cement, or concrete, and plaster surfaces, are rendered hydrophobic by applying to the surface thereof a solution of a hydrophobic agent thickened by admixture with from 1-25% by weight of a filler having a BET surface area of at least 50 m<SP>2</SP>/g, and removing any residue of filler from the surface after evaporation of the solvent. The hydrophobic agent is preferably an organo silicon compound e.g. an organo polysiloxane, a hydrolysable optionally halogenated alkyl or aryl silane or an alkali metal hydrocarbon siliconate (monomeric or polymeric) but may also be a synthetic resin or aliphatic hydrocarbon. The solvent may be water, an organic solvent (either water-immiscible or water-miscible), or a mixture of water and a water-miscible organic solvent e.g. an alcohol or ketone. The filler, which is preferably colourless and present as a visible suspension may be a silicon dioxide (pyrogenically produced, aerogel or precipitated), a pyrogenically produced titanium dioxide or a mixture. The fillers may carry organic or siliconorganic compounds adhering or chemically bonded to their surface. Trimethyl siloxy groups may be formed by reacting pyrogenically produced silicon dioxide with trimethyl ethoxy silane. The fillers may be admixed with other fillers having a surface area of less than 50 m<SP>2</SP>/g and are preferably present in an amount of 5-15% by weight based on the hydrophobic agent and solvent. The liquids may be applied to the building materials by spreading, spraying or trowelling. The residue of filler loosely adhering to the building material after evaporation of the solvent may be removed by brushing or by blowing with compressed air.

Title: Device for evaluating the difference between two inputs of variable magnitude
IPC: H04Q3/00
Filed: 1970-10-14
Abstract: 1293417 Metering telephone calls CTT COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS 14 Oct 1970 [14 Oct 1969] 48929/70 Heading H4K [Also in Division G4] A counter is set to hold the value of an increasing variable at one point of time and a register is set up to indicate the value of the variable at a later time, matching circuits detecting the difference between the values in the counter and the register to start a pulse generator which steps the counter until it matches the state of the register, the number of pulses needed to step the counter to equality being recorded by a further counter to indicate the difference between the two variables. The arrangement is applied to determining the difference between telephone or telegraph exchange clock times at the start and finish of a call, such times being delivered as codes at the end of a call. A short time elapses between the end of a call and the point at which start and finish time particulars are transferred to the arrangement for taking the difference. Advantage, in the way of reduced demand on intermediate storage space, is said to reside in sending only a fraction of the clock code output marking the end of a call, but sending direct from the exchange clock the complete clock code at the time of transfer of start and finish codes from intermediate stores. The arrangement for taking the difference will then hold the full code of the start time, a fraction of the code of the end time, and a full code of time of transfer. By advancing the start-time code step-by-step with the fraction of the end time code until the fraction of end time matches the corresponding fraction of the transfer time code, the starttime record is adjusted so that its difference, found by stepping it to coincidence with the transfer time, indicates call duration.

Title: A Preparation for the Production of Prints on Oxide Films artificially produced on Aluminium, and the Application Thereof
IPC: C09D11/02
Filed: 1967-10-27
Abstract: 1,199,607. Printing process. SANDOZ Ltd. 27 Oct., [27 Oct.,1967], No. 48946/67. Head ing B6C. [Also in Division C3] Prints are made on the surface of an aluminium (or alloy) sheet which has been oxidized, e.g. by chromate or anodic oxidation, with the aid of a composition (see Division C3) comprising a solution in an organic solvent of a watermiscible viscosity regulator selected from hydroxypropyl methyl cellulose, polyvinylpyrollidone or an acrylic acid or acrylamide polymer, together with a water-insoluble non- polymeric substance which is at least partially dissolved in the solvent and is substantially non-volatile up to 100‹ C. The composition optionally contains a water-insoluble dye. The dye-containing composition can be screen printed on to the oxide surface, followed by immersion in boiling water to fix the dyestuff into the oxide layer. The coating is partially removed in this stage, and is finally removed with cold water, leaving a dyed oxide layer. Compositions containing no dye are useful for forming the protective layer in a resist-dyeing process.

Title: Analogue to digital converter
IPC: H03M1/00
Filed: 1966-11-03
Abstract: 1,106,160. Analogue-to-digital converters. ADAGE Inc. 3 Nov., 1966 [4 April, 1966], No. 49258/66. Heading G4H. In an analogue to digital converter of the kind in which conversion is effected in coarse and fine steps, the gain of the input amplifier 26 being changed for the fine step, the input signal is applied to an analogue-to-digital converter 34 in the first step, the digital output being applied via store 64 to a digital-toanalogue converter 68, to obtain a coarse value which is subtracted from the input signal, the difference is then multiplied by 128 by the amplifier 26 and applied, in the second step, to the converter 34, the digital output of which is stored at 60. The digital signals obtained in the first conversion are applied through gates 52, enabled by programmer 46, to store 54 which may comprise a number of flip-flops. The outputs from store 54 actuate diode gates in converter 68 to switch positive current from terminal 70 and negative current from terminal 72 through weighted resistors 76a-76h. The result of the second conversion is entered into the store 60 via gates 58, also controlled by the programmer 46. The converter 34 accepts positive or negative signals, the sign being indicated by a sign bit S having the highest binary value. The other digits are in straight binary scale. For negative inputs the sign digit switches positive current from terminal 70 in the converter 68, the other digits being in 2's complement form so as to subtract an appropriate negative value to obtain positive analogue equivalent for subtraction at junction 100 from the negative input. For positive inputs the sign bit is " 0 " and negative values are switched by digital signals indicating the true value. The negative output is then subtracted from the positive input. In the first step the gain of the amplifier 26 is unity and is selected by the programmer 46. In the second step the amplifier gain is raised to 128 by switching in a different feed-back resistor 28. The most significant fine digit (2<SP>7</SP>) is therefore the same as the least significant coarse digit. These digits are added at 110 and the sum entered into the store 54 which has provision for carry between storage units. The outputs from the stores 54 and 60 are taken to a complementer 106 to obtain the true digital equivalent of the input. If the storage flip-flops have mark and space outputs the complementer is unnecessary.

Filed: 1972-10-30
Abstract: 1414524 Purifying exhaust gases S B JOHANSEN 30 Oct 1972 [29 Oct 1971] 49852/72 Heading F4B Gaseous fuels and flue gases, including exhaust from I.C. engines, are burnt in the presence of excess combustion air, the air and/or the gas being heated by heat exchange from the combustion products, the temperature of both the air and the gas before coming into contact with each other being maintained above the temperature of ignition of the mixture, the air and gas being fed separately to a reaction chamber so that a surface combustion takes place between them in the reaction chamber. In the form of Fig. 1 the reaction chamber 1 is extended by an exhaust chamber 2. Combustion air is fed from line 3 through a chamber 4 surrounding the reaction chamber 1 and exhaust chamber 2 whereby it is heated before entering the reaction chamber at 6 together with the gas which enters from a gas conduit 5. In a modification (Fig. 2, not shown) part or all of the air enters the reaction chamber via two tangential nozzles spaced from the gas conduit and being designed to cause turbulent flow. In the form of Fig. 3 the gas and air are fed to the reaction chamber through separate long interleaved ducts 8 and 6 so that they arrive at approximately the same temperature. The air passing along the line 3 is first preheated by the hot combustion products and then further heated in chamber 4. In another form, Fig. 4 (not shown), the gas also is heated by being passed through a chamber surrounding the chamber 4 at the top end of the reaction chamber. The gas is passed into the chamber tangentially so as to cause a turbulent flow through the heating chamber. Where the apparatus is to be used for burning excess carbon monoxide in the exhaust gases of an internal combustion engine, the inflow chamber 4 may be surrounded by an outer pressure-proof housing 24, Fig. 5, which damps fluctuations of pressure in the exhaust. The housing is filled with a heat-insulating and sound absorbing material 22 and the wall of chamber 4 is perforated at 21. The gases to be burned enter tangentially into chamber 16 and pass through a number of jets into the reaction chamber, each jet being surrounded by a circular air jet. Air enters at 3 and is heated in chamber 4 and at 27 further air enters the exhaust stream to reduce the temperature. In Fig. 7, the air is fed through openings 3<SP>1</SP> to a heat exchanger in chamber 2 formed by a number of thin pipes which end tangentially in the chamber 4. The amount of air entering is controlled by slide 28. In another form (Fig. 8, not shown) the heatexchanger pipes 30 are replaced by a chamber surrounding the exhaust chamber 2, there being a number of tubes crossing this chamber leading to the openings 21 to the absorbent filling 22. The amount of air provided should match the volume of gas to be burned, the air blower being coupled to the main shaft to the engine.
